DEFLECTOR-PLATE FOR GAS-STOVES.

SPECIFCATION forming` part of Letters Patent No. 554,528, dated February11, 1896.

Application filed September 13, 1895. Serial No. 562,459. (No model.)

T0 all whom t may concern:

Be it known that I, JOHN M. MURPHY, re

siding` at Danbury, in the county of Fairfield and State of Connecticut,have invented a new and Improved Deflecting-Plate for Gas- Stoves, ofwhich the following is a specification.

My invention relates to certain new and useful improvements indeflecting-valves for equalizing the force of distribution of gas andother vapors to burners; and it consists substantially of such featuresof arrangement, construction and combinations of parts as willhereinafter be first described in detail and then specifically pointedout in the appended claims.

One of the greatest difficulties experienced with the burners of gas andsimilar stoves is the unequal force with which the gas or Vapor is fedto the jet-orifices, the result being that in most instances the flameis greatest at the point of entrance of gas to the burner from thesupply-pipe. At opposite or intermediate points the flame and heatproduced is comparatively moderate or small. This unequal distributionof the gaseous fuel results 'furthermore in the rapid Wearing out of theburner at the point of communication thereof with the supplyepipe, owingto the greater intensity of heat at that point, and besides this aconsiderable quantity of the gas is wasted without effecting any goodresult. Furthermore, accordingly as the pressure of gas be greater orless, there is always some variation or fluctuation of the meter causedby the unequal consumption of the gas at the point of issuance from theburner, and this trouble frequently results in the payment by the userfor much more gas or fuel than has been actually consumed.

The object of the invention is to provide for the equable distributionof gas and like fuel throughout the entire burner, thereby overcomingthedefects above mentioned, substantially as will hereinafter more fullyappear on reference to the accompanying drawings, in Which- Figure l isa vertical sectional elevation of a vapor-burnerhaving my improvementsembodied in connection therewith. Fig. 2 is a top or plan view thereofwitha portion of the burner-top cut or broken-off so as to more clearlyindicate the interior disposition or arrangement of the equalizing ordeiiectingvalve. Fig. 3 represents, respectively, atop 55 view, a sideview, and a View in perspective of my improved equalizing or deflectingvalve.

In carrying my invention into effect I employ preferably the ordinaryform of circular 6o o r round vapor-burner, the same being composed of amain body constructed with a continuous chamber and closed over the topby a ring or cover which is provided on its under surface with an innerand outer series of radialribs or projections Which create Hameorificesbetween the ring and main body when said ring or cover is secured inplace. The said chamber is provided at any suitable point thereof withan opening into Which the gas 7o or vapor supply-pipe is placed orfitted airtight, and it is immediately at the point of communication ofthis supply-pipe with said chamber that my improved pressure-equalizin gor deflector valve is arranged or located. 7 5

The said valve is so constructed that a portion thereof extends downbefore the opening in the chamber in such manner that the force of thecurrent of gas or air entering the cham ber from the pipe is immediatelybroken and 8o a part of .such vapor Will becaused to first pass underthe opposite side of the Valve before it can proceed on its course tofill the chamber within the burner.

The said valve is so constructed as to divide 8 5 or separate thecurrent passing in not only to the right or left, which would be thenatural tendency in the normal condition of things, but into separatestreams, as it Were, thus supplying all of the flame or jet orifices 9oequally and with the same force The said equalizing or defiector valveis furthermore so constructed at its top as to cause the same quantityof gas or fuel to pass out through the orices Which cross over or passthe same, 9 5 and by this means the power of flame and in tensity ofheat is rendered practically uniform or equable throughout.

Reference being had to the accompanying drawings by the letters markedthereon, A roo represents the burner, which, as shown, is preferablycircular or round, and is formed or constructed with a continuous gas orvapor chamber c. The said chamber is closed at the top by means of aring or lid B, the under side of which is formed or provided with aseries of ribs or projections b and an outer series of' the same markedb', the two being concentrically arranged and constituting j et-oriicesc when the said ring or lid is secured in place, as seen in Fig. l.

C represents the gas or vapor supply-pipe entering` the side of thechamber a, the said pipe being supposed to lead from any suitablereservoir or supply.

D represents my improved pressure-equalizing or deflector valve, which,as shown, is located immediately at the point of connection orcommunication of the supply-pipe With the chamber. Thispressure-equalizing or deflector valve is constructed of a top portionor ledge (Z, which is practically straight at cl but curved inwardly atd, so as to create a space c between the same and the outer Wallv of thechamber, up through Which space sulficient gas may pass and escape tothe jet-orifices which pass or lie above said valve. The ends of thecurved portion d are formed into lugs or ears e', which are received bycorrespondingly-shaped recesses e2 in the upper edge of the outer Wallof the chamber a, and in this Way said valve is securelymaintained inplace against displacement. The said valve is also provided on its underside with a curved depending flange cf", which 'follows the generaldirection of the chamber a, and the ends of which flange gradually slopebackward toward the top portion or ledge d, which it intersects. ln usethis curved depending flange occupies a position centrally of thechamber a (see Fig. 2) with the effect of separating or dividing theincoming current into practically two separate streams; and, as saidportion or flange extends down somewhat within the plane of the openingof communication between the chamber-supply pipes (see Fig. l) it isevident that the operation and result Will be such as has hereinbeforebeen stated to be the cause.

From the foregoing description it is thought the nature and constructionof' my invention will be fully understood, and I desire to say thatimmaterial chan ges can be resorted to in the practice of the inventionwithout departing from the general scope and purposes intended. Forinstance, the depending portion or flange of the valve is only madecurved in order that it may conform in general direction to that of thechamber Within which it enters, but it is evident that if the generaldirection of the said chamber be made straight in a direct line, saidflange may be correspondingly formed.

Having thus described my invention, what l claim, and desire to secureby Letters Patent, is-

l. A pressure-equalizing or dellector plate for vapor-burners the sameconsisting of an ripper ledge or portion, and a depending [lange orportion for entering the vapor-chamber ol' the burner, substantially asdescribed.

2. A pressure-equalizing or deflector plate for vapor-burners the sameconsisting of an upper portion or ledge straight on one side andrecessed or curved inwardly on the other and having a depending liangefor extending into the vapor-chamber, of a burner substantially asdescribed.

3. A pressure-equalizing or deflector plate for vapor-burners, the sameconsisting of an upper portion or ledge having on its under side acurved depending flange for entering and conforming to the generaldirection ol the vapor-chamber of a round or circularvaporburner,substantially as shown and for the purposes described.

4t. The combination in a vapor-burner having a circular vapor-chamber ofa pressureequalizing or deector plate located, at the point ofcommunication of the said supplypipe with said chamber and having acurved depending flange entering the chamber, substantially as and forthe purposes set i'orth.

5. The combination in a vapor-burner having a circularvapor-chamberprovided around its upper edge with a series ofjet-orifices, of a pressure-regulating or dedector plate located at thepoint of communication of the supply-pipe With said chamber, the saidplate having a top or ledge recessed or curved inwardly on one of itsedges, and provided on its inside with a curved depending portion orflange entering the chamber substantially as shown and for the purposesdescribed.

G. The combination in a vapor-burner having a circular vapor-chamber, ofa ring provided on its under side With an inner and an outerconcentrically-arranged set of ribs or projections and apressure-regulating or deflecting plate, located at the point ofcommunication of the supply-pipe with said chamber, the said platehaving a top or ledge recessed or curved inwardly on one of its edgesand provided on the under side with a curved depending portion or flangeentering the chamber substantially as described.
